The EU just classified ChatGPT, Reddit, and Roblox as "very large online platforms" under its Digital Services Act, which means they're now subject to the bloc's strictest online safety rules. All three hit the 45 million monthly user threshold in Europe that triggers this designation. They'll have to remove illegal content, protect minors' privacy and security, and face fines up to 6 percent of global revenue if they don't comply. The European Commission announced this on Monday, with tech chief Henna Virkkunen framing it as holding these services accountable given their massive reach across EU citizens. This decision extends the DSA's reach into generative AI territory, building on earlier moves like the investigation into Elon Musk's Grok chatbot. The EU has been figuring out how its existing digital regulations apply to AI services as they've rapidly evolved, and this classification signals Brussels won't treat AI chatbots as some special exception. ChatGPT, Reddit, and Roblox now have until the end of December to actually implement these new obligations. What makes this significant is the enforcement teeth behind it. The 6 percent global revenue fine is substantial enough to matter for these companies — it's not a slap on the wrist. The EU is essentially saying that scale and user impact determine regulatory burden, not whether you're a traditional social platform or an AI service. This probably won't be the last time the Commission applies DSA rules to AI companies operating in Europe.
